Question

solve.

x = 10
-8x - 10y = 20

(\square, \square)

submit

Explanation:

Step1: Substitute \( x = 10 \) into the second equation

We know \( x = 10 \), so substitute \( x \) in \( -8x - 10y = 20 \).
\( -8(10) - 10y = 20 \)

Step2: Simplify the left - hand side

\( -80 - 10y = 20 \)

Step3: Add 80 to both sides

\( -10y = 20 + 80 \)
\( -10y = 100 \)

Step4: Solve for \( y \)

Divide both sides by - 10: \( y=\frac{100}{-10}=-10 \)

Answer:

\((10, - 10)\)
